Claims. (Cl. 5-210) This invention relates to furniture and more particularly to beds.

It has been a disadvantage with double beds used in homes that one person sleeping in a double bed is likely to keep another person sleeping with him awake because the movements of one person Will cause the bed to vibrate and his bedfellow will be disturbed. The movements of one person cause the mattress to pull and thereby disturb the other person. Twin beds have the advantage that only one person sleeps in the bed and there is no danger of his being awakened by movements of a bedfellow. However, the average home today is not large enough to accommodate twin beds. Also, when two children are allowed to sleep in the samedouble bed, when one child moves around during the night, he is likely to awaken the other child. Beds in general have had the disadvantage that when the frame of the bed is moved or struck, the shock is transmitted to the person or persons sleeping therein. I

I have discovered that the frequency range usually encountered in beds due to movement of persons thereon or due to accidental impacts on the bed frames is within the range of one to two hundred cycles per minute. I have also discovered that it is possible to design resilient mounting means to support the mattresses of a bed whereby all vibration within the frequency range will be eliminated and will not be transmitted to the mattresses from the bed frame.

Another object of this invention is to provide a double bed which has all the advantage of a twin bed and also many of the advantages of a double bed.

Another object of the invention is to provide a bed wherein the occupant will not be disturbed when an object strikes the frame of the bed.

Another object of the invention is to provide a bed which will have two individual mattresses and box springs which will be independent of each other and will not allow the circulation of drafts of air to flow between the mattresses and dissipate body heat of occupants of the bed.

A further object is to provide a double bed wherein mattresses occupied by two persons are separately and independently supported.

Another object of the invention is to provide a double bed wherein the movement of one occupant will not vibrate the portion of the bed occupied by another occuant. p These and other detailed objects will appear from the following descriptions and are obtained by the structure illustrated in the accompanying drawings, in which:

Fig. 1 is a transverse sectional view of a bed;

Fig. 2 is a longitudinal view showing one of the supports for the bed shown in Fig. 1;

Fig. 3 is a top view of another embodiment of a support for a bed;

Fig. 4 is a side view of an embodiment of a support; and

Fig. 5 is a detailed view of a vibration mounting.

Referring now to the drawings, Fig. 1 shows a bed frame 1 having mattresses 2 and 3 and transverse members .6. and 7 which are angular in cross section as shown and which may be disposed transversely with one member at each end ofthe bed and have side plate members extending along the edges to retain the mattresses in place. The bed is provided with side rails 11 and 12. Instead .of the conventional slats which would ordinarily rest on seats 13 and 14, the bed is provided with a transverse member 20 supported at either end 21 and 22 by resilient mountings 23 and 24. The resilient mountings 23 andi24 are shown in more particular detail in Fig. 5. The mountings 23, 24, 25, 26, 27, and 28 are made up of end members 30 and 31 having heads 32 and 33 mounted to a body member 34 made of rubber or a like resilient material. to the resilient mounts 23 and 24 by nuts or like fastening means 29. By proper design procedure, the members shown in Fig. 5 can be designed to eliminate vibration in the range of frequency of one cycle to two hundred cycles per minute.

The resilient members 23 and 24 are secured at one end thereof to the transverse member 20 and at the other end thereof to the brackets 41 and 42. The other end of the bracket members 41 and 42 is secured to the side rails 11 and 12 of the bed by means of the bolts 43 which hold the bracket members 41 and 42 to the strips 45 in frictional engaging relationship. The strips 45 are secured to the side rails 11 and 12 of the bed by means of screws such as 47 or any other gluing or welding fastening means. The bed 1 is provided with bedposts 50 which are supported on casters 51. The side rails 11 and 12, brackets 41 and 42, and strips 45 make up the frame 1 of the bed.

Figs. 3 and 4 show another embodiment of the invention wherein the headboard 6%) of the bed supports the side rails 61 having strip members 62 secured thereto at 63. The strip members 62 are notched at 64 and the cross member 20 of the bed is supported on strip 62 through bracket member 63. The bracket member 63 is secured to the transverse member 20 through a torsional resilient member 65. The torsional member 65 has a bolt 66 which is secured against rotation in the bracket member 67 and has a resilient member 68 made of rubber or like material bonded to said bolt member 66. The resilient member 68 is bonded at the outside thereof to the bracket member 63 so that a weight placed on the frame 20 will tend to twist the resilient member 68 and cause a sheering stress in the rubber material between the bolt 66 and the bracket 63.

Between the transverse members 6 and 7 is provided a strip of sponge rubber 70. This strip of sponge rubber prevents air currents from circulating up from below the mattresses through the opening 71 between the mattres'ses. When a person is sleeping on each of the mattresses 2 and 3 and a blanket is spread over both persons and hangs clown over the edges 72 and 73 of the mattresses, no air currents will circulate up through the space 71 between the mattresses.

Details of construction may be varied substantially without departing from the spirit of the invention and the exclusive use of novel structure as described as coming within the scope of the claims is contemplated.

What I claim is:

1. A bed comprising spaced, longitudinally extending side rails, a first transverse member having its ends supported on said side rails, spaced resilient mounting members supported on said first transverse member, two spaced, transversely aligned second transverse members, each said second transverse member being supported on at least two said resilient mounting members, two spaced bed spring units, means to restrain said bed spring units The transverse bar 20 is secured verse members, each said spring unit being supported on" one of said second transverse members, the ends of said first transverse member being supported on said side rails by means of resilient members, and means to support a second end of said spring units.

2. The bed recited in claim 1 wherein said resilient members comprise blocks of rubber.

3. A bed comprising spaced, longitudinally extending side rails, brackets attached to the inner edges of said side rails, the lower ends of said brackets being turned inwardly to form horizontally disposed portions, a first resilient member supported on each of said horizontal portions, a first transverse member at each end of said bed supported on said first resilient members, spaced resilient members supported on said first transverse members, laterally spaced, transversely aligned second resilient members supported on the upper sides of said first transverse members, two laterally spaced second transverse members supported on each said first transverse member with said second resilient members therebetween and attached thereto, two bed spring units each supported on two of said second transverse members, and means to restrain said spring units against lateral movement relative to said second transverse members.

4. The bed recited in claim 3 wherein said resilient members each comprise a block of rubber like material disposed between and attached to spaced metallic members, said metallic members each being attached to one of said first transverse members and to one of said second transverse members.

5. The bed recited in claim 3 wherein a strip of foam rubber is disposed between said second transverse members and between said spring units in engagement with said second transverse members and extends longitudinally, forming a seal against the flow of air between said transverse members.
